Abstract

152,699. Hardcastle, J. J. J., and Scipeo, A. C. July 21, 1919. Pianoforte soundboards and sound-intensifiers. -The backs of pianoforte soundboards a are provided with resonant tubes c of aluminium-steel alloy, bolted to a secondary bridge d which is made sufficiently high to keep the tubes clear of the ordinary ribs b. To adapt the tubes to existing soundboards, a grooved block is fixed so that the securing-bolt passes through into the bridge.
